1. Break-even analysis—the budget plan that operates your business, determines at what point your revenues and your losses are going to be equal i. BEP

• For finding dollar equivalent: BEP = FC / CR • For finding unit equivalent: BEP = FC / CM • CR = CM / SP or CR = 1 – VR • CM = SP – VC • VR = VC / SP • BEP increase à increased costs, decreased profit

b. Types 1. Operational Budget—used to forecast future needs and costs 2. Capital Budget—also called investment appraisal, more for long term investments (property, machinery)

of 1.55 • Ex: Need 10 employees? Multiply by 1.55 for actual number

2. Productivity i. Meals/labor hour = total meals served/day divided by labor hours/day ii. Minutes/meal = labor min/day divided by total meals/day

3. Pay i. Payroll cost/day = sum of hourly rate of each employee x hours worked by all ii. Payroll cost/meal = total daily payroll divided by meals/day iii. Labor cost/meal = total labor cost (both productive and non-productive) / meals iv. Total labor cost/day = total payroll + total of all other direct (fringe benefits etc.)/day v. Sales = cost of labor / labor cost %

b. Food—easiest to control, fluctuates the most c. Capital

1. Current Assets—things that can be converted to cash 2. Capital ownership—interests and earnings retained, when revenue is high than expenses put money
